Replacing a lamp
If the screen becomes dark, the color looks unusual, or
the LAMP indicator on the front of the monitor flashes,
it is time to replace the lamp with a new one.
Disposal of the Used Lamp
Sony regards protection of the environment as
extremely important.
Kindly put the used lamp in the new lamp's package
and send it to the sales company whose address
appears on the new lamp's guaranty card.
Before replacement
• Be sure to use the Sony XL-100U lamp unit (not supplied) for
replacement. Use of other lamps causes damage to the
monitor.
• Do not remove the lamp for any purpose other than
replacement.
• Before replacement, be sure to turn off the monitor and unplug
the power cord.
• When replacing the lamp, let it cool down completely, as the
surface of the lamp remains hot for at least 30 minutes after the
power has been switched off.
• Do not leave the removed lamp near the inflammable
materials.
• Do not pour water onto the removed lamp, nor put any object
inside the lamp.
• Do not put inflammable materials and metal objects inside the
lamp receptacle on the monitor, after removing the lamp. Do
not touch the receptacle.
• Fit the new lamp securely, otherwise the screen may become
dark, or it may cause fire.
